6.FAQ 

●What’s PID control?

A:PID control strictly and precisely control temperature and movement of top head of Dinghua touch screen BGA rework machine. This is essential to increase success rate of repairing chips and PCB.

Today's closed-loop automatic control technology is based on the concept of feedback to reduce uncertainty. The elements of the feedback theory include three parts: measurement, comparison, and execution. The key to the measurement is the actual value of the controlled variable, which is compared with the expected value. Use this deviation to correct the system response and perform the adjustment control. In engineering practice, the most widely used regulator control law is proportional, integral, differential control, referred to as PID control, also known as PID regulation.

The PID controller (proportional-integral-derivative controller) is a common feedback loop component in industrial control applications and consists of a proportional element P, an integral element I, and a differential element D. The basis of PID control is proportional control; integral control can eliminate steady-state errors, but it may increase overshoot; differential control can speed up the response of large inertial systems and weaken the overshoot trend.

The key to this theory and application is how to correctly correct the system after making the correct measurements and comparisons.

PID (proportional, integral, derivative) controllers have been used for nearly 100 years as the earliest practical controllers and are still the most widely used industrial controllers. The PID controller is simple and easy to understand, and does not require precise system model and other prerequisites before use, and thus becomes the most widely used controller.
